The Blades defender has been sidelinedsince the game against Ipswich on 10th September but manager Neil Warnock has confirmed that he could be ready for a return to the side when United take on Wolves at the end of next week.
"Craig had trouble with his Achilles and it turned out to be ganglion," Warnock told the club's official website.
"He had it removed on Thursday and should be available to start training this week in a hope that he could be available to face Wolves after the international break."
